Actor Vin Diesel had penned a new tribute to his late friend and Fast & Furious co-star Paul Walker.

The 46-year-old star took to Facebook to post a touching tribute to Walker who tragically died in a car crash in November (2013).

Alongside a picture of Walker with Diesel's brother, also called Paul, he posted: "Pablo (Walker) and my mother would have deep conversations... she claimed, that it was no accident that this on-screen duo has come to define brotherhood in Our millennium. You see... the other guy in the photo is also named Paul... and although they look more alike, he is actually my twin brother."

He added: "God knows we will need all of you to complete this intense experience called Seven. Though this may be one of the hardest things I have had to do in my career, I can't help but to think... that it will also be the most significant."
